Belstaff Sideline Jacket - Blue - Checkered - XXL

No, you must never machine wash or dry clean a waxed cotton jacket, as it will destroy the finish.

It depends on usage, but generally once a year or whenever you notice water no longer beads up on the fabric surface.

It is designed as a versatile layer. It is excellent for wind resistance and spring or autumn weather, but you may need to wear a heavy base layer during harsh winter temperatures.

Yes, the Sideline jacket is designed with a regular fit specifically to be worn as an outer layer over knitwear.

The jacket uses 6oz. British Millerian waxed cotton, known for its historic quality and weather-resistant performance.

The wax has likely worn off through use; apply a fresh layer of reproofing wax to the fabric.

Use a soft, damp sponge or cloth to gently wipe the area; do not use soaps or detergents.

This can happen if too much wax is applied; allow the jacket to dry thoroughly in a warm room after any rewaxing treatment before wearing.
